One common theme is growth. Luke's growth as a character, both in intelligence and in his relationship with Professor Layton. Another theme is mystery - after all, they are known for solving mysteries in the original games.
No. Writing sexual fanfiction about a character like Professor Layton is inappropriate. Professor Layton is a character from a family - friendly game series. Fanfiction should respect the nature and intended audience of the original work, and creating such adult - themed content goes against that respect.
One great 'professor layton x luke fanfiction' could be 'The Adventures Beyond the Puzzle'. It really delves into their relationship and takes them on a new mystery-solving journey. Another one might be 'Luke's Growth' which focuses on how Luke develops under Professor Layton's guidance in a very heartwarming way.
One interesting concept could be alternate universes where the characters have different roles or abilities. For example, Layton might be a villain instead of a detective.
One major ethical issue is the disrespect to the original creators and the intended audience. The creators designed Professor Layton to be a character in a non - sexual context, and by creating sexual fanfiction, it shows a lack of respect for their vision. Also, it can make the fan community an uncomfortable place for those who don't want to be exposed to such adult - themed content.
First, you should have a good understanding of the original Professor Layton series. Know the characters, their personalities, and the overall tone of the story. For example, Layton is known for his gentlemanly and intelligent demeanor.
To develop Professor Layton, you can focus on his intellectual side more. Show how he analyzes every situation and how his vast knowledge helps him make decisions. For Luke, you can show his growth. Maybe at the start he's a bit timid in solving really difficult puzzles, but as the story progresses, he becomes more confident. For example, you can have a scene where Luke is the one who figures out a crucial puzzle all by himself.
One idea could be that they go on a journey to a mysterious land that's not on any map. In this land, they encounter strange creatures and have to solve puzzles that are based on the unique culture there. Another could be a time - travel plot where they end up in the past and have to figure out how to get back while also helping the people of that era with their wisdom. Maybe a third idea could be that Luke gets kidnapped and Professor Layton has to use all his skills and knowledge to rescue him, facing many challenges along the way.
If it's a crossover with the Final Fantasy series, characters like Cloud Strife could be included. Cloud's brooding nature and combat skills would contrast with Professor Layton's calm and cerebral approach. Tifa Lockhart could also be part of it, providing her own brand of strength and determination.
